Question

determine whether the ordered pair is a solution of the inequality:
(-3,4); 9x+y<-8
In this case is the ordered pair a solution? yes or no

Answer 1

determine whether the ordered pair is a solution of the inequality:
(-3,4); 9x+y<-8
In this case is the ordered pair a solution? yes or no

Answer 2

substitute values. If LS<RS then it is a solution
-27+4 is less than -8

Answer 3

can you show the work

Answer 4

work is exactly what mathguy wrote. replace x by -3, y by 4 and see if your result it less than -8. you write
\[9\times -3 + 4<-8\]
\[-27+4,-8\]
\[-23< -8\] true!

Answer 5

thanks you guys

Answer 6

7x + 8 > or = to - 48 or 5x + 2 > or = to - 8
the solution of the compound inequality is
{x|x>=to ---?
